IMPROVEMENT IN HOSE-NOZZLES.

Specification forming part of Letters Patent No. 166,654, dated August 10, 1875; application filed May 4, 1875.

To atl whom it may concern:

Be it known that I, WALTER THOMSON, of Detroit, in the county of Wayne and State oi' Michigan, have invented an Improvement in Horse-Nozzles, of which the following is a specification:

The nature of my invention relates to an improvement in nozzles of that class that are to be used on a garden-hose, and are so constructed that, at the will of the operator, the water can be discharged as a single jet or in the form of spray; and its object is to so construct the nozzle as to dispense with all eX- ternal cocks or valves. To this end it consists in the peculiar construction of the nozzle-head and a hanged diaphragm, to which it is axially pivoted, the said diaphragm being screwed on the end of the nozzle-pipe proper.

Figure l is a perspective View. Fig. 2 is a longitudinal section, showing the head to discharge in a single `jet, the section being taken through a0 in Fig. 3, which is a longitudinal section at y y, the nozzle-head being turned so as to discharge the water through the rose. Fig. 4 is a det-ached longitudinal section through the nozzle-head at x. Fig. 5 is a plan ot' the base or inner end of the nozzlehead. Fig. 6 is a plan of the face or outer end of the hanged diaphragm. Fig. 7 is a section of the same at z z. Fig. 8 is a perspective view of the washer between the nut and the diaphragm.

In the drawing, A represents a nozzle-pipe, threaded at the outer end to receive a ring or ange, B, in which is formed a diaphragm, B, serrated on the outer face to receive and hold stationary a leather washer or packing, a. C is a cup-shaped nozzle-head, having a screwstein, c, at the center of its base, which projects through a hole in the center of the diaphragm, in which there are two ports, b b,

diametrically opposite each other. The head is secured on the diaphragm by a nut and jam-nut, d d. Between the nut and the under side of the diaphragm a lock-washer, cl2, is interposed, and so fitted to the spindle that the head may berotatedwithout screwing up or loosening the nuts. In the outer end ot' the head there is a central jet-pipe, G1, which projects through the center of a rose, C2, sprung into a groove in the outer end of the cup. Two curved passages, e e, are cored in the base Aof the head, which unite and intersect the bore of the pipe G1. Two other passages, e', diametrically opposite each other, are drilled through the head into the space under the rose. All the passages have the same radius as the ports b. The base of the cup is received within the upper flange of the diaphragm B, and rests upon the packing-leather a, which prevents the leakage of water around the outside of the cup-base.

To discharge a single jet of Water, the head should be turned so as to bring the passages e e coincident with the ports b b. To discharge water through the rose, turn the head so that the water will pass from the ports b through the passages e c to the rose. If the head be turned to any other position the low of water will be shut oi'.

What I claim as my invention is In a hose-nozzle, substantially as described, the combination ofthe rose and jet head with the double-hanged diaphragm, pivoted thereto, and an interveningA packing-leather, severally provided with the ports and passages, substantially as described, for the purposes specified.

WALTER THOMSON.
